Model CSC12

The CCI Model CSC12 shall be constructed of circular carbon steel bands, which bolt together forming a shell around the carrier pipe. The casing spacer shall be lined with a ribbed EPDM extrusion with a retaining section that overlaps the edges of the shell and prevents slippage. The casing spacer shall be designed with risers and runners to support the carrier pipe within the casing and maintain a minimum clearance of 1.0 in. between the casing ID and the carrier pipe OD. 

The runners shall be Glass Filled Polymer with ends of the runners beveled to facilitate installation over rough weld beads or the weld ends of misaligned or deformed casing pipe. The runners shall be attached to support structures (risers) at appropriate positions to properly support the carrier pipe within the casing and to ease installation. They shall have a minimum length of 11.0 in. and a minimum width of 2.0 in. 

The shell shall be manufactured of 12.0 in. wide, hot rolled, pickled, and oiled 14-gauge carbon steel. The riser shall be constructed of hot rolled, pickled, and oiled 10-gauge carbon steel, 10.75 in. minimum lengths with a height to be determined based on the annular space between the carrier pipe OD and the casing ID. 

Recommended positioning of the casing spacers is one placed 1-2 feet on either side of the bell joint and one every 6-8 feet apart thereafter for a total of three casing spacers per joint. CCI engineering reserves the right to recommend spacing according to application.
